摘要: The information on general combining ability (GCA) and specific (SCA) is important for hybrid development. objective of this study was to determine GCA SCA effects number ear whole weight eight sweet corn inbred lines. Four lines with small ears (S) extracted from KKU-WTMsh population four large (L) KKU-WSHCsh populations were crossed in a diallel fashion produce 56 F1 hybrids. hybrids the evaluated randomized complete block design three replications rainy season 2011 dry 2011/12. Data recorded at green harvest. GCA, reciprocal significant weight. variance more than indicating that predominance additive gene action but higher MS37 had positive high effect ear, whereas DKA good combiner MS59×MS136 MS59×MS88 highest season, MS37×MS88 best genotype trait season. DKA×MS37 performed while DKA×MS88 between inbreds average weights 16,581 17,294 kg ha seasons, respectively, crosses those within ears. prolific group. Therefore, development new single cross order increase per plant could be achieved through breeding different sizes.
